Circumstances of DisappearanceBingham was last seen in London, England on November 7, 1974.
On that night, his children's nanny, Sandra Rivett, was murdered at the home of his estranged wife, the Countess Lucan. The following evening, police visited the hospital bed of Mrs. Bingham. She had suffered from shock, loss of blood and seven severe scalp wounds. She told them that she had been watching television with her daughter that evening in the second-floor bedroom. The nanny went downstairs to make some tea. After about 15 minutes, Lady Lucan began to wonder what was taking Sandra so long. She told investigators that she went downstairs to find the nanny and was then attacked. She was certain that the assailant was her husband, and that he had mistaken the nanny for his estranged wife.
Almost one week following the attacks, police issued a warrant for the arrest of Lucan. Police mounted an extensive search for Lucan, but to no avail. He was never found.
On November 10, police found the Ford Corsair Lord Lucan was driving the night of the murder, abandoned some 16 miles away near the docks of Newhaven. Following the discovery of the car, police searched extensively for Lucan. He had disappeared.
In October 1999, Lucan was ruled officially dead, even though his body had not been found.
